8.9 Knowledge-Trees


K-lines can form societies. How can we keep them orderly (e.g., in nice hierarchies)? Minsky's solution: level-band theory again. "When making a new K-line memory, do not connect it to all the K-lines active at the time but only to those that are active within a certain level-band."

Can this be done without specifying what "level" means for K-lines? Minsky says yes: "Something like this will happen automatically, simply because the new K-line societies will tend to inherit whatever hierarchy already existed among the original agents that become connected to those K-lines."

New problems emerge, though. "This policy of connecting new K-lines to old ones must be used in moderation. Otherwise, no new agents would ever be included in our memories. Furthermore, it should not always be requried to produce simple, orderly hierarchy-trees." But the level-band idea still needs to be adopted.

(NB: There must be some representation of time in Minsky's system, so that it can identify K-lines that were "recently active".)
